D1 thanks for sharing this katcher driver. I am trying to make a circuit these days which is basically a synchronized katcher. I take the thin pulse out of my synchronization board and I drive an IRfp460which in turn feeds the dc voltage to my katcher just for that brief moment. If it works I'll post the schematic.

We could come to some kind of consensus if you'd accept that atoms are made out of Aether, too....or everything is made out of Aether.

As long as you think that matter is a different substance, like fish swimming in an aquarium full of Aether, then we will "transmit on different channels".

Nick,
if you use for you kacher a tv or monitor transistor from horizontal deflection driver as I remember you said previously it most likely won't work (oscillate)
for kacher because of its very low h_fe coefficient. Better you get one of this 2SC5200 or MJE15030.
Can you tell more precisely the code marked on your kacer transistor ?

Hi guys
Void, yes i still use the blue box of Allega's to create the synchronized thin pulse. The problem for me is that my yoke doesn't have more space for winding a 40T secondary so to feed with 130V-150V DC my IRFP460. (Which triggers Tesla coil). In addition i don't want to make a second Push pull as Allega did, in a separate yoke core just for that. So what i am testing right now is feeding my Katcher as i told you with a high voltage (200V) kickback out of my mosfet when i drive it with the synchronized pulse. But, two days now i can't start my katcher to oscillate even with continues 24V supply (as Nick). I will try again today. I use a 2sc5200 (Toshiba).

(If someone has any idea on any improvement please feel free to share it)

Hi Nick. I doubt there is anything special about the kacher circuit itself.
You should be fine with the kacher circuit you already have working. I think the quality of
your earth ground and how the output from the grenade coil is being used
is probably what is more important in that circuit setup.

That circuit setup from Ruslan which does not use the PWM driver is probably not so far off from
what Nelson is doing as far as the basic operating principle. I am basing this on this recent statement from Nelson:
"I just try to help understand that results that people search  are not able to be achieved by induction..."
(http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg478997/#msg478997)

In Ruslan's circuit setup without the PWM driver, the output capacitor is being charged via the strong
electric field from the high voltage end of the tesla coil. The switching of the output capacitor with short
nanosecond range duration pulses will be the most tricky part I think. Then there is the matter of the output
transformer which Ruslan may have explained some details about in the video, but without a line by line
translation of what Ruslan said in the video about the device (Ruslan seemed to provide a fair amount of details),
you will likely be guessing about the output transformer details. We also don't know which frequency Ruslan
was pulsing the output capacitor at, unless Ruslan mentioned that in Russian in the video. Unfortunately that
is a fairly long video, 23.5 minutes, so getting a line by line translation into English might well not happen
any time soon. A translation of any important details about how Ruslan said he is switching the output
capacitor, and any details about the output transformer would be nice though.    

In this circuit the first stage is just an on time for the first FET through the coil _---_--- like this it inverts the signal so it's output is off, unless it's input is triggered correctly it's off when it should be on ??
